Euripedes is a fictional student of Aristotle. Following his teacher's line of thought, Euripedes proudly declares his commitment to civic association, that the true test of a person's worth is in what the individual does, not in personal characteristics. Euripedes fails to examine the fact that the principle of civic association excludes:

women.

Explanation:

The answer is "women".

Aristotle was the master of Euripedes. Euripides was a Greek tragic playwright. He wrote many plays in the past. Some of his famous plays are Hippolytus, Medea, The Bacchae, etc.

Euripedes, following his master's belief also declares that he is committed to civic association. But he fail to examine that the principle of civic association excludes women, which is a drawback.

The civic association which Euripedes is associated with does not include the women society in it.

Thus the answer is - - "women".
